I have stayed out of this discussion for obvious reasons.
However, the service suggested by Simon provides me with services I do not want and so far as I can tell does not provide me with what I do want. The difference in cost, that is clearly important for many, is for me at least irrelevant.
My experience of broadband where I live, is that when it works its great but from time to time it doesn't, some times for hours, some times for days.
As I am currently organised, without a phone line, I can use my mobile and go to the local bar to access the internet and still watch TV via my satellite link.
But in the scheme that is suggested, if I lose my phone line I have nothing and, almost irrespective of any other issue, that is why I would not chose such a solution.
